TIN TYPE-MACHINE.

T 0 all whom "it may concern:

Be it known that I, FRANK B. DICKASON, citizen of the United States, residing at Shreveport, in the parish of Caddo and State of Louisiana, have invented new and useful Improvements in Tintype-Machines, of which the following is a specification.

My invention pertains to photography, and consists in the peculiar and advantageous machine, hereinafter described and claimed, for making photographic pictures and more especially what are commonly known as dry tin-types.

In the drawings, accompanying and forming part of this specification: Figure 1 is a longitudinal vertical section of the machine constituting the best practical embodiment of my invention of which I am cognizant, as the same appears when its parts are in their normal positions. Fig. 2 is a plan view of the same, taken with the lid of the casing in a raised position. Fig. 3 is a view illustrating the parts in the positions the same occupy when the magnet is in the magazine in position to attract a plate to it. Fig. 4 is a view like Fig. 1 showing the parts in the positions they occupy when the mag net has been moved to and downwardly through the plate-receiver to the lowermost position of the magnet, and the platereceiver has chuted the plate into the de veloping receptacle. v

Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is the casing of my novel machine, which is open throughout at its top and is equipped with a suitable hinged lid B At its forward end the casing is provided with a lens of fixed or universal focus a, but I would have it understood in this connection that in lieu of said lens the ordinary well known bellows mounting a double lens may be employed without affecting my invention. I have, however, deemed it unnecessary to illustrate the said bellows and double lens, as the same per 86 form no part of my invention and are simply employed, when deemed expedient, to facilitate focusing. At its Specification of Letters Patent.

rear end the casing A is provided with a sight opening 7), normally closed by a gravitating shutter c. The said shutter 0 may be opened by a finger of the operator introduced through the opening 6, or in any other suitable manner compatible with the purpose of my invention. It will also be observed by reference to Figs. 1, 3 and 4;, that the casing A is provided at its rear end with a subcasing (Z having a hinged lid 0 of its own. Movable in a revoluble manner through an I opening in the partition f between the casing A and the sub-casing (Z is a developing receptacle B, having a diametrical partition 9, and also having a handle it, which latter is carried by a ournal 2' bearing in the bottom wall of the casing, and is designed to enable the operator of the machine to conveniently turn the receptacle B without admitting light to the interior of the casing.

Located in the lower portion of the casing A and at the end of said casing remote from the developing receptacle B is a plate magazine C. The said magazine may be of any construction compatible with the purpose of my invention, but I prefer to detachably connect it to the bottom of the casing through the medium of a screw j, frictional contact or other suitable means, this in order that a depleted magazine may be removed and a fully-charged magazine put in its place. It will be noted that in the present embodiment of my invention, the magazine C is provided with a lid D, hinged at is, and that the said lid D is provided in turn with an eye Z. The said eye Z loosely receives an arm m on a rock-shaft n, which rock-shaft is disposed transversely of the machine and is provided with another and shorter arm This latter is connected through the link 1" with the long arm of a vertically swinging lever s, fulcrumed at t and having a beveled short arm a, designed to be engaged by a cam 12 on a transverse shaft D The said shaft D has an arm E, and fixedly connected with said arm is a horseshoe or other suitable magnet F.

Fixedly connected to one end of the rockshaft D is a crank G which is arranged outside the casing A and is designed to be engaged with and disengaged from a keeper H, also arranged outside the casing A. lVhen the crank G- is engaged with the keeper H, the arm E extends vertically upward from the shaft D and when said crank G is disengaged from the keeper H and is moved forward, the shaft D will be turned in the same direction, and the arm E and the magnet F will be swung forwardly and downwardly. Incidental to said movement of the shaft D arm E and magnet F, the cam 11, by acting against the beveled arm of the lever s, will, through the medium of said lever s, the link 1" and the arms p and m of the rock-shaft a, raise the lid D of the magazine C to the position shown in Fig. 3 so as to enable the magnet F to attract to it the uppermost of the superposed plates (prefera bly tin types I) in the magazine. On the reverse movement of the crank G back to its engagement with the keeper H, the magnet F and the tin-type thereon will be raised to a vertical position with the face of the tintype opposite and exposed to the lens a; and during the last part of said movement of the magnet, the cam 71 will release the forward arm of the lever s, whereupon a spring Q0 acting upwardly against said arm will quickly close the magazine lid D.

A ground-glass plate J is carried by a frame K, hinged at L to one side wall of the casing A, and a spring M is employed to move the frame K and plate. J to and yieldingly retain the same alongside the said wall of the casing. It will be noticed, however, that a lever N is connected through a link P with an arm Q on the frame K, and also that said lever N is positioned to be engaged by the cam o. In consequence of this, it will be observed that when the magnet F and the tin-type thereon are moved rear :ardly from the vertical position hereinbefore mentioned, the cam e by acting against the lever N will swing the frame K and the ground-glass plate therein to a position opposite the lens a in which position the ground-glass plate can be used incidentally to the focusing of the next subject of which a picture is to be taken. I would also state at this point that incidental to the upward and forward movement of the magnet F to the vertical position, where the crank G engages the keeper H, the cam a; will release the lever N, whereupon the spring M will. quickly move the frame K and plate J to and yieldingly hold the same against the side wall of the casing and out of the way. When the magnet F and the tintype thereon have been retained in the vertical position hereinbefore mentioned until exposure of the plate is made, the crank G is disengaged from the keeper H and swung downwardly and rearwardly until the arm E and the magnet F pass through the open ing R in the flanged plate-receiver S. At this time the outer end of the magnetcomes in contact with a magnet bar or device T for making the magnet permanent, and when the magnet is moved downwardly beyond the said device T, the tin-type is left on the plate or tin-type receiver S. Then incidentally to the continued downward movement of the arm E and the magnet F, the said arm E depresses a crank U on a transversely disposed rock-shaft V, which rock-shaft V has an arm lV, connected through a link X with an arm Y on the rock-shaft Z by which the receiver S is carried, and consequently it will be observed that the forward end of the receiver S is elevated to enable the receiver to chute the tin-type into one compartment of the developing receptacle B. The said receptacle 3 is then turned to move the compartment containing the tin-type into the sub-casing (Z, and while the development of the said tin-type is taking place, the operation described may be repeated and a second tintype deposited in that compartment of the receptacle B which is in communication with the interior of the casing A. At this time the first mentioned tin-type is ready to be removed from the receptacle B, and subsequent to said removal, the receptacle l3 is turned to move the compartment containing the second tin-type into the sub-casing (Z, and so on. The hinged lid 0 of the sul: casing (Z obviously permits of the tin-types being removed with facility from the described compartments of the receptacle B.

It will be gathered from the foregoing that when the magnet F is in its normal position, the ground-glass plate J rests in the position shown in Figs. 1 and 2, and consequently by looking through the sight opening Z) of the machine, the operator can focus the same. Then by swinging the crank G upwardly, forwardly and downwardly, the lid D of the magazine C is opened, and the magnet F is positioned to enable it to at tract the uppermost plate or tin-type in the magazine C; also, incidental to the upward and forward movement of the crank G, the spring M moves the frame K and the ground-glass plate J to a position alongside of the side wall of the casing A. On "the return movement of the crank G from its foremost position, the said crank is engaged and held by the keeper H, and the face of the tin-type is in position opposite the lens until exposure. The crank G is then disengaged from the keeper H and permitted to move rearwardly and downwardly to its normal position, and during said movement, the cam '21 by acting against the lever N. will return the ground-glass plate J to its working position opposite the lens. When the said crank G is in its normal position, the end of the magnet bears on the yielding bar T, and the tin-type rests on the receiver S, and then by further downward and rearward movement of the crank G, the tin-type is separated from the magnet and left on the receiver S, and the forward end of the said receiver S is elevated, whereupon the tin-type will be chuted into the adjacent compartment in the receptacle B. It will further be gathered from the fore going that when the parts of the machine are in the normal position shown in Figs. 1 and 2, the lid B may be opened without exposing the tin-types, as the said types are always protected except when the mechanism is in action.

As before stated, the construction herein illustrated and described constitutes the best practical embodiment of my invention that I have as yet devised, but it is obvious that in the future practice of the invention such changes or modifications may be made as do not involve departure from the scope of my invention as defined in the claims appended.
